To all whom t may concer/n: Y

Beit lmownthat l, ANTHONY LANzETTA, a'citizenrof the United yStates, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Aeroplanes, of which the Vfollowing is a specification. l

This invention relates to aeroplanes and has for its object means to support or raise any weight by the arrangement of a special plane with deflectors on divisions of the 'plane which give a certain advantage for air drafts and to avoid o'verstrain, the opening between each division having beneath it a second planewith stabilizing means surrounding it and comprising hinged planes which may be deflected and held at a desired angle as long as it may be necessary to provide for regulating the plane when off the horizontal position, but which means is released when normal conditions arerestored. Means are also provided for directingthe machine upward or downward and the rudder is for certain advantageous reasons mounted on the ton of the device, and the car for the engine and drivermay be located between the stationary planeswhile floats are provided to sustain the machine upon the water, all of which with other. objects and'details will be more fully described in the following.specification, set forth in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of the improved aeroplane.

Fig. 2 is a ,Fie- Fig. of the F ig. means.

Fig. 6 is a side view of the stabilizing trol. Y e

lF ig. 7 is a plan view of the same.

Fig. 8 is a horizontal sectional View befront elevation of the same.

3 is a side elevation.

t is an enlarged fragmentary view fin. 5 is a'plan view of the rudder locking low the upper planes and car.

The device comprises 'a frame of uprights 10 and horizontal `stringersll mounted on wheels 12 and carrying a car 13 in which is arranged the engine for the propeller 14 and whatever control mechanism may be necessary forvthe aeroplane. p

Longitudinal bars 15 are supported at the top of the device by the uprights and withv the intermediate sheathings 16' comprise a Specification of Letters Patent.

plane of two sections 17 and 18, with downwardly deflected vrear edges, which is stationary and forms the upper plane in case the device is a bi-plane, or it may be in itself a monoplane. Suitable guys and braces connect these members of the frame to form a substantial construction and the rear ends of the plane sections are curved downward to cause buoyancv to float 17 and 1S as the machine moves through the air. As a rear stabilizer, a tail or rudder, such as shown in n. p 'Y nig. 'o may be used and have appropriate steering means. Y

On the top of the above mentioned plane is a circular raceway- 19 in which travel rollers 20 supporting the front and rear ends of the iin 21 while lateral arms 22 at each side Vof the n also have rollers 20 at their outer ends to travel in the raceway and retain the fin in its upright position. Depending Vfrom the iin and below the raceway isa stem 23 controlled by a hand wheel 24 that is within reach of the aviator and has near its lower end the ratchet wheels 25 and 26 withteeth reverse to each other and adapted to be engaged by pawls 27 and 28 pivoted at a fixed point adjacent the ratchet wheels and normally locking the iin rigidly at any desired direction and operated by the pedals 29. When it becomes necessary to change the course of the machine the approp-riate pawl is raised out of engagement with its ratchet wheel Vand the fin may be turned in the direction permitted by the release. .as will be seen in itin'. 3 the wheel ,and stem are located in the entrance of the car and in front of the aviators seat while the panels 29 are at his feet. e

The rollers 2O are introduced into the raceway through` an opening 20 and have upper and lower tracks, while the movement of the fin is limited to ninety degrees by stops 21 located around the raceways and intercepting the stems carrying the rollers. One of these stops may be used to cover the opening` 20 and confine the rollers within the raceway.

At the lower part of the frame 10 and above the wheels are floats or pontoons 30V to buoy the machine on the water in case that it is found desirable to use it as a hydro-` .Y .the angular end of the lever 36.

directly below the opening which separates them is a second stationary plane 3lV which like the upper plane is deflected downward at its rear end Vfor buoyancy. Y Adjacent the lower plane 31 are four pivotedplanes, two, 32 and 33 at theront and rear respectively o1" the machine while the planes 34 and 35 are pivoted to the side of the same. The aXis of each of these planes is near its inner side leaving a large sweep at the top edge and they are controlled by levers 36 lcarrying at their ends suspending rods 37.

The operation of the pivoted planes is shown in Fig. 6 where it will be seen that the lever 36 is pivoted to the bracket 38 of a box 39 adjacent the aviators seat in the car and its inner end 40 is oli' set at an angle and has a Slot 41. Through the box 39 passes a rack bar 42 with a head 43 at one end and a pinV 44 at the other end to connect it with .This rack bar is pressed inward by a spring 45 that surrounds it but it is automatically locked by the pawl 46 to hold the planes in their normal horizontal position Vand the pawl is so retained by a weight 47 hanging from its axle.

VIf'this end of the aeroplane should drop below the horizontal, the weight would cause the pawl to leave the rack bar and the spring 45 Would force the bar backward, raising the lever 36 to the position shown in dotted lines and raising the plane 34 to an angle to act as a plane to support the device if it should drop in that direction.

VThe same construction and arrangement is l applied to the planes 32, 33 and 35 to effect an automatic release and for the instant po sitioningoi a plane to retard a sudden abnormalv movement and to prevent a lurch which would throw the machine off its hori- Vzontal and wreck it.

It is obvious that when the aviator again gets control of his machine and rights it he may V"push the head 43 and rack bar 42 outward and the plane will resume its normal position. A rod 48 may be used to operate the pawl independently of the weight.

,In addition ,to the use-ot these pivoted planes Vas a stabilizer means they may alsov horizontal position so as to give a larger Varea of surface andthe iront and rear planes areV allowed to take an inclined rudder position in order to allow the aeroplane an upward movement.

lWhen it is desired to take spiral courses the side planes are released and moved by means of the automatic levers so as to bring the upward side into a higher operating position vwhilethe, lower side Vremains in the horizontal or neutral position.

Should the machine fall into an air pocket and overbalance, the weight and pawl, permitting theoperation of the control levers of the side stabilizers, would immediately release and bring the plane back to a neutral position, thereby retarding any abnormal movement and'righting the machine.

The lin may be set in any desired direction and held there by the pawls, which with the steering wheels are not only convenient to the aviator but simple and compact. The machine may be widened at each end by the addition oi panels to increase its capacity and the number ot planes may be increased Vto make it a triplane.

lThe .location of the iin on the top ofthe upper plane permits of the ready movement of the pivoted planes and does not interfere with their functions.

It is obvious thatv other modifications and'V arrangements of theparts ot the device may be resorted to without departing from the essential features above described or from the scope of the appended claims.

What l claim as new is:

l. ln an aeroplane,the combination with a frame, a plane divided into sections with a space between them, a lower plane beneath the space, stabilizers at the sides of the lower plane, means for detlecting theV stabilizers, means .for releasing the detlecting means, and means for checking the deiiecting means.
